Core adjustment mechanisms for adjusting the length of a motion transmitting core element or conduit are well-known in the remote control art. The typical assembly, as illustrated in U.S. Pat. No. 3,572,159 to Tschanz, includes a slider member slideably supported in a housing with a spring interposed between the slider and the housing to bias the slider in one direction with respect to the housing in order to take up slack in the core element or the conduit, whichever attaches to the slider. A locking member on the housing can lock the slider in a given position with respect to the housing, if desired.
In some core adjust mechanisms the slider and the housing enclose the spring. Such an arrangement is taught in U.S. Pat. No. 4,854,186 to Jakob et al. Enclosing the spring protects the spring from the environment and, at the same time, makes the overall core adjust package more compact. However, the design in the Jakob patent is by no means the most efficient, i.e. compact design for such core adjustment mechanisms.
